Do your spell realms affect at all how much damage your pets do with spells? For example, would a Druid with a fire realm of 80's conjures cast harder than a Druid with a realm of 20s?

In short...no.

Druid realms currently have no effect on your pet's strength. However, every time your pet successfully hits a mob it will count toward raising your realm in whatever element your pet is. Pet casting will not go toward raising realms.

Really? I could have sworn that this changed when pet damage was recoded.
